Description

Technical Field

[0001] This utility model relates to the field of polishing machine technology, specifically to an optical sight lens polishing machine. Background Technology

[0002] The primary function of an optical sight is to use optical lenses to create an image, superimposing the target image and the aiming line onto the same focal plane. Even slight eye deviation will not affect the aiming point. A sight consists of several parts, including an objective lens, an eyepiece, and an inverted image lens. These include various convex and concave lenses, and to ensure clarity, the lenses are mostly made of glass.

[0003] Chinese Patent CN217596692U discloses an edge grinding machine for processing optical sight lenses. The machine includes a base, a vertical plate fixedly connected to the output end of a second electric telescopic rod, a second motor fixedly mounted on one side of the vertical plate, and a connecting sleeve fixedly connected to the output shaft of the second motor through the vertical plate. A connecting post is inserted into the connecting sleeve, and a grinding disc is fixedly connected to one end of the connecting post. Symmetrical locking grooves are formed on the outer side of the connecting post, and U-shaped blocks are symmetrically fixedly mounted on the outer side of the connecting sleeve. A fastener that engages with the locking groove is rotatably connected to the inner side of the U-shaped block, and a built-in torsion spring is fixedly connected between the fastener and the U-shaped block. In this invention, the grinding disc and the connecting sleeve are connected by the connecting post. By rotating the fastener, the built-in torsion spring undergoes elastic deformation, allowing one end of the fastener to disengage from the locking groove of the connecting post, thus facilitating the removal of the connecting post from the connecting sleeve and the replacement of the grinding disc.
